Converting of 2 DVB-S/S2 modulated 
input signals into 2 COFDM modulated DVB-T channels.

  • common interface
  • TS processing:

           service multiplexing - any input to any output 
           PCR restamping
           PSI/SI regeneration
           NIT generation
           PMT version monitoring

  • Web control and SNMP monitoring
  • loop through RF distributing at input and output
  • DIN rail or wall mounting
  • robust die-cast housing
  • Connectors:

           RF input/output - type F
           Ethernet control interface - RJ-45
           2xCI ports - PCMCIA (tdx420C, ttx420C)
           screw terminal block for DC entry
           power distribution bus
